My honda civic 1996 speedometer not working properly, nidle stack

if your speedometer is working,and the odometer is not,you will need to have the odometer replaced for it works off the speedometer

The "needle at 20MPH" is a sure-fire indicator -- it's the speedometer head. This is a common problem in this year.

I haven't found a fix other than replacing the speedometer head, sorry.

the only thing that is related is the d4/rough gear changing
speed/ rpm malfunction is caused by your speed sensor on the trani (common problem) change it

Most likely a speed sensor is going bad (most cars and truck do not use mechanical speedometer cables anymore) most sensors are located near the differential in rwd cars or near the drive shaft on the transmission. Best bet is to get a Haynes manual for your car to help locate the speed sensor. Remove it and take it to the auto parts store so you can visually compare it to the replacement. Install the new speed sensor and it should restore your speedometer and odometer.

Your cars speedometer has a broken or frayed cable replace it the Tach is separate from the speedometer/odometer and will work on its own

if both go then its the sensor ,but if car is a 98 then it could be a cable or a speedo cable crive worn out

Does it hang out at 18-20MPH, regardless of your speed?
Mine did the same thing. The problem was an open circuit inside the gauge itself, and there's no repair for the parts. You'll need to get a replacement speedometer gauge, or simply buy a replacement instrument cluster.


If it's not doing the "20mph" thing, then it's possible that you just need a new engine speed sensor. This is located on the rear of the engine block, and is hard but not impossible to reach and replace.

One way to test is to set the car on cruise control when the speedometer is working. If the speedometer cuts out ,but the cruise is still able to maintain your speed, then the sensor is OK and the problem is the gauge. If the cruise control also cuts out, then the sensor is bad.

speed sensor servo common on hondas weve done many due to the d4 light and eratic speedo

I already replaced the speed sensor but still it wont work! how to determine the cause of the problem

Look on the wiring harness it plugs in on top of the transmission
make sure all the wires are together. If every thing is ok with the wiring, The sensor is the only thing it could be. A gook used spedometer sensor from the junk yard will work this sensor dosent take a lot of abuse so a good used one will be cheap and work just fine. This is a job you can do your self and save a lot of money. I had the same problem with my 95 civic
